新生儿高胆红素血症可引起心、脑、肝、肾等多器官的损害,研究发现对心肌的损害主要表现在心肌酶谱、心电图、心功能和心脏病理等方面[1]。评价心肌是否受到损害,常用的指标是心肌酶谱,通过黄疸对心肌细胞的损伤,比较心肌酶谱、肌钙蛋白(CTNI)、心电图的QT离散度(QTd)的对比分 Neonatal hyperbilirubinemia can cause heart, brain, liver, kidney and other organ damage, the study found that myocardial damage mainly in myocardial enzymes, ECG, cardiac function and cardiac pathology [1]. To evaluate whether the myocardium is damaged or not, the commonly used index is the myocardial enzyme spectrum, and the comparison of myocardial enzyme spectrum, troponin (CTNI), and QT dispersion of electrocardiogram (QTd) was performed by jaundice on cardiomyocyte injury
